Given numbers are 871,645,559,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 871,645,559,338 is 14606670.
Find LCM of 871,645,559,338 with Prime Factorization
| 13 | 871, 645, 559, 338 |
| 43 | 67, 645, 43, 26 |
| 67, 15, 1, 26 |
Multiply the prime numbers at the bottom and the left side.
13 x 43 x 67 x 15 x 1 x 26 = 14606670
Therefore, the lowest common multiple of 871,645,559,338 is 14606670.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
871 x 645 x 559 x 338 = 106146670890
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
871 : 1, 13, 67, 871
645 : 1, 3, 5, 15, 43, 129, 215, 645
559 : 1, 13, 43, 559
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,645,559,338, is 1.
Now, the common factors can be found like this.
871:13x 67
645:3x 5x 43
559:13x 43
338:2x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 13x 43 = 7267
Therefore, the value for common factors is 7267.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 106146670890/(1x7267)
LCM = 106146670890/7267
LCM = 14606670
Thus, we can understand that the LCM of 871,645,559,338 is 14606670.
